The force which acts between charged particles in chemical reactions and elsewhere

The force responsible for all electromagnetic interactions, such as those which hold atoms and molecules together. It acts on anything with an electric charge, its force carrier is the photon, and its range is infinite. Electromagnetic force is created by the interaction of electric and magnetic fields, and can be attractive or repulsive, as in causing particles with like charges to repel one another and those with opposing charges to attract each other. It is one of the four fundamental forces of nature, the others being the gravitational force, the weak force, and the strong force.
